Analog Joystick – derives speed (velocity) and direction from joystick position. Motor velocity is proportional to joystick distance from center and the settable speed ranges. Simultaneous 2-axis motion is accomplished with two VXMs. An input switch allows a single joystick to toggle between 2 motors of a 4 motor system. The Joystick is 1 million cycle design in a convenient hand-held
enclosure with a 10 foot cable.

Heavy duty 2-axis Joystick – is a digital joystick that controls two axes. For more robust commercial/industrial applications with a larger desk mount control box. Operational design is similar to the digital joystick.

Heavy Duty Remote Jog Station - RThe Jog Station remotely moves (jogs) a single axis VXM-1 or VXM-1J Controller via push buttons. It offers convenient one-hand operation. Push the button to move in one direction. Release to stop. Push the other button to move in the opposite direction. Release to stop.

Limit Switches on Velmex Motorized Linear Stages

Limit Switches are electro-mechanical devices that regulate the motion on positioning devices. On Velmex products they are primarily used to stop/turn off the motor when activated preventing over-travel of the carriage/slider. They also can be used to send an event signal. Limits connect with controllers, such as the Velmex VXM™ Step Motor Controller. Velmex uses several different types.

• Adjustable (moveable) limits, which are standard on BiSlide Assemblies and optional on XSlide and UniSlide Assemblies.

• Fixed end of travel limits, which are standard on XSlide Assemblies and optional on UniSlide Assemblies. These are not adjustable.

• Internal limits which are only available on the UniSlide MB90 Series.

• Home switches, which actually reference a point rather than limit travel, are used on Rotary Tables and can be used on XSlide Assemblies.

It is possible to purchase motor-driven Velmex stages without limits, however, it is not recommended and it may effect the warranty should you incur any damage.

The following at-a-glance chart outlines the Velmex Stage and what limits can be used.

BiSlide® Limits

Adjustable limits (standard) - Velmex BiSlide Assemblies have two adjustable limit switches mounted in a track on the side rib of the assembly to prevent over-travel. An optional third limit switch can be added between the two standard limits and used as an adjustable home switch. (This would require a different controller.)

BiSlide limit switches are referenced by either a "-21" or "-31" at the end of the model number. On Parallel-Coupled BiSlide Assemblies, the limits would be eliminated from one of the two linear stages that comprise the assembly.

UniSlide® Limits

Adjustable Limits (Optional) - Mounted on the side rib of Velmex UniSlide Assemblies, these two switches can be used to stop travel. These are ordered as a separate part number (OBLS).

Available on all UniSlide Series and UniSlide XY tables

The adjustable limits are located inside a rail that runs the length of the UniSlide® base. A 1/4" cam plate is added to the carriage/slide that depresses the cam when the carriage encounteres it and activates the switch. Thumb locks affix the limit in the proper position. (Pictured: 2 Limits on MA15 Series)

Fixed, End-of-travel Limits (Optional) (MA40, MA60, MB90)- These push button switches are fixed on the side rib of Velmex Unislide Assemblies. They are not adjustable. On all UniSlide Series except the MA15 and MA25 the limits are built into the end plate of the slide. On the MA15 and MA25 Series they are outboard switches affixed to the side rib. These are ordered as a separate part number which begins 3-934.

Internal Limits (MB90 "J" Only - Standard) - The internal limits on the MB90 Series consist of two switches, a control rod mounted along side the lead screw with two moveable brass collars and cover atop an additional 3" of dovetail base as shown. The collars are positioned on the control rod to activate the limits. The internal limits on the MA90 Series UniSlide Assembly are referenced by the letter "J" at the end.

XSlide™ Limits

Fixed, End-of-travel Limits (Standard) - XSlide Assemblies have two fixed, end-of-travel limit switches built into the end plates. XSlide fixed limit switches are referenced by either a "-21" or "-71" at the end of the model number.

Adjustable Limits (Optional) - Moveable limit switches can be added as an option to motorized XSlide Assemblies. These switches can be used to stop travel within the overall travel distance of the XSlide. When installed the adjustable limits reduce travel distance by 1.2" (3.05 cm). These are ordered as a separate part number (XSW-X-PR).

Magnetic Reed Home Switch (Optional) - A magnetic reed home switch sets a reference point to return the carriage to home (starting) position. This is moveable. Ordered as a separate part number (XSW-M).

Mechanical home switches can be added to UniSlide and BiSlide linear stages. Switches used in this manner require an additional controller.

Rotary Table Limits

Magnetic Home Switch (Optional) - A magnetic reed home switch sets a reference point to return the carriage to home (starting) position. This is moveable. Ordered as a separate part number (XSW-M).

Limit Switches (Optional) - Using two zero-reference (home) switches on a Rotary Table creates limits that restrict travel to a specific degree arc.
